Mechanical Advantage and Friction
Professors A and B compare the mechanical advantage of an inclined plane with that of a lever. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.
The Lever
Eureka! demonstrates the principle of the lever: "The longer the arm of the lever to which force is applied, the less that force need be." Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.
The Screw and The Wheel
This program provides examples and definitions of a screw and a wheel; a screw is simply a twisted inclined plane; a wheel is simply a circular lever, whose fulcrum has become an axle. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.
Eureka! Episode 2 - Mass
Building on the concept of inertia, Eureka! adds the factor of mass, tells how it's measured, and shows how it differs from size. Concept: Inertia increases with mass. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.
Weight vs. Mass
Eureka! explains the difference between weight and mass, and shows how only mass is the same on the moon and on the earth. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level. Run time 04:46.
Centripetal Force: the Roller Coaster
What can we learn about physics from an amusement park ride? This videosegment, produced for Teachers' Domain, uses roller coaster footage to demonstrate that what really keeps people pinned to their seats as a roller coaster hurtles through a loop isn't just the seat belts, it's centripetal force. To reinforce this important scientific principle,a physics teacher successfully swings a cup of water around his head without spilling a drop. Run time 04:40.
Physics with Mr. Noon: Electric Current, Part 1
This was filmed inside a class room and the camera is a little shaky. Here are some high school physics demonstrations dealing with current electricity.
Conservation of Energy
The myth of the energy crisis. According to one of the major laws of physics, energy is neither created nor destroyed.
Demo of Action and Reaction
See action and reaction demonstrated with a tug of war. The force of the tug of war is measured with scales. This video is a demonstration explained by a teacher, Paul Hewitt, in front of the classroom. This is a brief clip from the DVD series "Conceptual Physics." Run time 01:35.
Learning As We Grow: Development and Learning -Session 2
This program examines the concept of readiness for learning and
illustrates how developmental pathways — including physical, cognitive, and linguistic — all play a part in students’ learning. Featured are a first-grade teacher, a seventh- and eighth-grade science teacher, and a senior physics teacher, with expert commentary from University of California at Santa Cruz professor Roland Tharp and Yale University professor James P. Comer.
Workshop 2: Drag Races
Forces can help put objects into motion and can also bring moving objects to a stop. In this workshop, fifth-grade students explore the physics of motion using plastic cars with strings and washers attached to provide a pulling force. The students test the speed of the vehicles and explain what forces bring the vehicles to a stop, as the cars collide with and displace ba
Dennis Hong - My Seven Species of Robot
At TEDxNASA, Dennis Hong introduces seven award-winnning, all-terrain robots -- like the humanoid, soccer-playing DARwIn and the cliff-gripping CLIMBeR -- all built by his team at RoMeLa, Virginia Tech. Watch to the end to hear the five creative secrets to his lab's incredible technical success. Dennis Hong is the founder and director of RoMeLa -- a Virginia Tech robotics lab that has pioneered several breakthroughs in robot design and engineering. Robots are often inspired by nature, incorporat
Toward Quantum Computing - PDF - December 9, 2009
Lunch 'n Learn presentation: Imagine a computer that made direct use of quantum mechanical phenomena. Such a machine would likely operate exponentially faster than our present computers.
Zahid Hasan is leading an international scientific collaboration that has observed an exciting and strange behavior in electrons' spin within a new material that could be harnessed to transform computing and electronics. The team believes that the discovery is an advancement in the fundamental physics of quantu

The Sun: A Laboratory for Astrophysics
Prof. Dr. Svetlana Berdyugina (Kiepenheuer-Institut für Sonnenphysik, Freiburg): The Sun is unique to us. It is the only star which we can explore in unprecedented detail. Understanding physical processes taking place on the Sun is of fundamental importance for insights into the stellar structure and evolution, generation of magnetic fields in the universe as well as star and planet formation. In this talk I will give an overview of some recent achievements in solar physics and their implicatio
The Contribution Of Econophysics To The Modeling Of Financial Markets
Prof. Dr. Rosario N. Montegna (Dipartimento di Fisica, Univ. of Palermo): Since more than 15 years, a group of physicists have been investigating economic and financial systems. Among these studies, a special attention has been devoted to financial markets. These studies are using tools and concepts of statistical physics. In this talk I will present an overview of some results obtained by our research group in this field. Specifically, I will discuss the multivariate nature of the dynamics of a
22.058 Principles of Medical Imaging (MIT)
An introduction to the principles of tomographic imaging and its applications. It includes a series of lectures with a parallel set of recitations that provide demonstrations of basic principles.

Réduction de la mortalité maternelle - Dakar 2010 : Introduction au colloque. (audio)
Le président de séance rappelle que ce colloque est un moment de réflexion pour confronter les approches et harmoniser le langage. La sexualité humaine est un objet social complexe qui, dans toutes les sociétés du monde, articule le langage, les affects et la physiologie.
La sexualité humaine, à la différence de la sexualité animale, dépasse la fonction de reproduction. Nous sommes des êtres de langage et de société. Le terme même de "reproduction" est trop
